To enable RSS hashing in the NIC, the PCSD bit must be set.
By default, this is never set when RXCSUM is disabled - which
causes problems higher up in the stack.
While here improve the RXCSUM flag assignments when enabling or
disabling IFCAP_RXCSUM.

so the only thing remaining for lock to protect inside the callout

Commit message of the identical change in Linux driver says:
"When an I2C HID device is powered off during system sleep, as a result
of removing its power resources (by the ACPI core) the interrupt line
might go low as well. This results inadvertent interrupts."
This change fixes suspend/resume on Asus S510UQ laptops.
While here add a couple of typo fixes as well as a slight change to the
iichid_attach() code to have the power_on flag set properly.

The driver was derived from code contributed by Intel, and modified

Use of smp_rendezvous_cpus() instead of sched_bind() allows to not
block indefinitely if target CPU is running some thread with higher
priority, while all we need is single rdmsr/wrmsr instruction call.
I guess it should also be much cheaper than full thread migration.

Add checks for req->ir_compcode errors in ipmi_reset_watchdog() and

It was written for Nehalem and Westmere, with minor but incomplete
updates for Sandy Bridge in 78d763a29b. The uncore architecture
changed significantly with this generation, bringing new layouts and
locations for some MSRs.
Misprogramming these MSRs in ucp_start_pmc() may panic the system, and
this is trivially reproducible via pmcstat(8) on at least Broadwell and
Haswell. Disable the class on these CPUs until it can be updated more
completely and leave a TODO comment detailing some of the work required.
Note that the nclasses value for Broadwell was already incorrect and
doesn't need changing.
The result is that any uncore events listed by pmcstat -L will no longer
be allocatable, but this is already the case for newer generations of
Intel CPUs.

libpmc/hwpmc: fix issues with arm64 pmu-events support
Due to a mis-merge, the changes committed to libpmc never called
pmu_parse_event(), or set pm->pm_ev. However, this field shouldn't be
used to carry the actual pmc event code anyway, as it is expected to
contain the index into the pmu event array (otherwise, it breaks event
name lookup in pmclog_get_event()). Add a new MD field,
pm_md.pm_md_config, to pass the raw event code to arm64_allocate_pmc().
Additionally, the change made to pmc_md_op_pmcallocate was incorrect, as
this is a union, not a struct. Restore the proper padding size.
